Maintenance yarn winding machines of the type mentioned work completely automatically. However, such winding machines cannot last longer Time through automatically operated in the intended way, because it accumulates excessive amounts of fluff and other foreign bodies on the critical guide, clamping, testing and sensing organs of the machine, so that these organs do not work properly work Although it is already known to move movable blowing devices within such winding machines, however, the performance of such devices is so poor that the air currents emitted by the devices are only one ■ Jerk up the fiber flight and return to the more accessible one Spread the upper surfaces of the machines and the supply package. Furthermore, there is the cross-section, the speed and the reduction of the supplied air currents from such Kind that it is not possible with the help of these air currents to prevent the fiber flight from the more critical and somewhat more strongly shielded ones remove the lower parts of the winding machines. Furthermore, there is a tendency in the textile industry to reduce the working speed of winding machines to increase. The faster a yarn runs through a winding machine, the more it loses Yarn fiber parts, and the more important it becomes, the deposited fiber fly from the critical parts of the automatic Remove winding machines.

The most critical parts of an automatic winding machine include the yarn guiding and sensing elements, which are usually " have the form of mutually movable, interlocking grids or grids, which normally rest on one another

OÖ961Ö / O785

and are biased against the intervening yarn. the neighboring thread tensioning devices are also quite endangered? they are usually in the form of a rotating disc to which the yarn is normally pressed elastically by a tensioning device. In the case of wheels, operation of the monitoring device, while the device detects the two ends of a broken yarn and tied them together, the grids or The grids are separated and the clamping element is lifted off the associated disc. Build-up of IPaser waste on the grilles or grids can prevent the grids from being more strongly engaged after the yarn breaks, so that the Grates do not do their job, which is to provide one Detect yarn breakage, due to which it is necessary to operate the monitoring device. If too big Set the amount of paser between the disc and the clamping element, the Gars.not on the correct winding tension held while it runs to the associated winder, so that a package of uneven density is obtained.

Each turning element of an automatic winding machine has the shape of an aniek plate or a loop catcher and forms a further "very critical element which is used to pull the yarn through" when a thicker section of thread enters the test element! this way the thicker section is eliminated, maä.

of the test organ, but the fiber waste also forms bundles on the yarn, which ^{have to be removed by the x} rüforgan or, together with the ΰ-arn, get to the winding body.

Since the blowing devices known up to now are not sufficient, in order to clean the critical parts mentioned, it has hitherto been necessary to frequently hand-work the parts concerned submerging hoses with high pressure Clean compressed air. A typical factory setup required all automatic winders to be run at intervals of to stand still for about four hours and clean them by hand; this resulted in a time consumption of about 15 minutes Cleaning about fifty take-up heads. Still, it was in this case also required accumulations of fiber waste from these critical between cleaning operations Parts to remove. It cannot be avoided here to shut down the winding machines during the overall cleaning process, since the personnel is endangered by the working parts of the machines, and because of the powerful air flow from the hand moving compressed air hose causes the yarn to break or relax.

The invention now provides a novel method for cleaning automatic winding machines for textile material, This experience enables the use of movable nozzles that emit fine air currents, which swing onto the critical ones Surfaces of the winding machines are directed * here the air flows have such a small cross-section and such high speed that very good cleaning of the machines

is achieved without the thread to be spooled or the thread that extends from the supply reels to the usual holding means close to the path of the gripping members of the monitoring device, disadvantageous to influence.

An object of the invention is to provide a novel method for removing fiber debris from critical surfaces to provide an automatic winding machine or a series of winding machines, comprising measures to make one or several moving, swinging, to generate a small cross-section of air currents and to cause these air currents to repeat itself automatically move along the winding machine or series of winding machines, the air currents so on the critical surfaces of the Winding machine or the machine series are directed that the fiber waste properly removed from the critical surfaces without the operation of the winding machine or the machine series and without endangering the yarn being processed or the yarn supply.

Another object of the invention is to provide a method of removing fiber scraps from parts or surfaces of none of take-up heads and a monitoring device an automatic winding machine for textile material during operation, the parts mentioned being the Garnführuhgs-, Testing and sensing elements include, which are arranged between the yarn storage bodies and the winding bodies, as well as the Yarn-grasping and connecting organs, which are connected with the management,

Testing and sensing organs work together; the invention Procedure involves action to get one to move at high speed direct moving air currents onto these surfaces and cause the air currents to automatically follow the row of winding heads move while the air currents are essentially be swiveled back and forth transversely to their direction of movement, as well as measures to prevent these air currents so frequently, with such a running speed and such an oscillation frequency automatically to bring about the effect that the mentioned Surfaces are kept essentially free of fiber waste for a long time.

The invention also provides measures to remove the fiber waste to remove which have been removed from the mentioned areas and are deposited on the ground} serves this purpose a movable vacuum cleaner that moves with the air currents and includes one or more suction nozzles that rotate move in the immediate vicinity of the floor to suck up the fiber waste from the floor and feed it to a collection device, which moves together with the fine air currents.

. To the stated goals as well as other goals among the most diverse ^ operating conditions when! cleaning automatic To achieve dishwashers it has been found necessary to combine several important features.

Of particular importance is the fact that with high-speed air currents are used, i.e. air currents that have a speed on the surfaces to be cleaned from about 600 to about 2,700 m / min or more

009818/0785

- 7 - ■ ^1A -29 376

In order to achieve such a speed on the surfaces to be cleaned • Achieve, it is expedient to use a flow velocity the air at the nozzles is on the order of about 1800 to to work about 3600 m / min, which depends on the - between the nozzles and the surfaces to be cleaned as well as after the obstacles formed by parts of the machine, which the nozzles must pass without being obstructed will.

if the fiber waste is to be properly removed, it is also important to use fine air currents, i.e. Air streams emitted from small nozzle openings, the diameter of which is preferably of the order of about 25 mm if you use several nozzles separated by small distances and the opening of each nozzle is small holds while the air exits at high speed For each air flow there is a very small effective area at the point to be cleaned, so that the air flow is at the can arrange and regulate surfaces to be cleaned exactly in the required "manner, without the operation of the winding machine is disturbed

For the perfect cleaning of critical surfaces of automatic winding machines, it is necessary to clean the fine, To sweep high-speed air currents back and forth in planes that are perpendicular to the direction of movement the cleaning device run when the device moves along the Lieihe von Aufepulköpfe. In other words, the air currents are constantly moving back and forth, in the

008818/0785

- 8 - 1A-29 376

essentially at right angles to the longitudinal direction of movement of the cleaning device. The vibration speed is sufficiently high compared to the running speed of the cleaning device, so that there is a sufficiently small longitudinal movement distance covered by each air stream during the period of oscillation will.

Usually, a blower speed of between about 9 and about 15 meters per minute is preferred. This low Speed in connection with the lateral swiveling movement of the various air streams ensures that paser waste which are lying on or on the parts of the winding machine to be cleaned can be properly removed.

In the drawings, the numeral 10 generally designates a typical automatic winder or a series thereof Machines in which the method according to the invention can be used. The machine 10 is representative of various types automatic winding machines, e.g. of the makes Barber-Colman Barcomatic, Foster-Müeller or Leesona Uniconer, and in the present case Case shows a Schlafhorst Autoconer as an example. Since the winder 10 is generally of known construction only the most important components are considered in the following, whereby in particular those components and actuators are dealt with, which must be kept free from excessive accumulations of fiber waste.

The winding machine comprises several arranged in a row Spooling heads or itfickelaggregate, which bezeiohnet a total of 11

009818/0785

- 10 - 1A-29 376

are; Each winding head is provided on the front with a magazine or storage container 12 for several (yarn bodies or filled bobbins 13. The operator of the machine supplements the supply of yarn bodies 13 in the magazine 12 from a container 14, which is opened by the operator along a suitable Guide 15 is moved, which extends along the front of the machine 10. When inserting the supply yarn bodies 13 into the iaa _e azin 12, the operator guides each yarn end Y from the relevant supply body 13 to the front edge of a plate-shaped deflector 16 shown in FIG and places the end of the yarn near the upper end of a yarn suction pipe 17.

Usually a suitable guide plate is arranged near the upper end of the suction or catching tube 17 so that the Operator can more easily guide the yarn ends into the immediate vicinity of the upper end of the tube, but this plate is not shown in Fig. 6 since it would cover other parts of the machine to be described. The pipe 17 for collecting the yarn ends extend downwards and backwards and are connected to a rigid suction channel 20 as shown in FIGS. 1, 2 and 3, which extends along the machine 10, and in which by means of known means, not shown here, in the head end are arranged on the machine, a negative pressure is maintained

During each bobbin change, a closure member 22, which is normally the upper end of the catching tube, is shown in FIG. 6 17 closes automatically enough from the pipe mouth

009818 / 078S

- 11 - 1A-29 576.

lifted so that the yarn ends Y can be sucked into the upper end of the tube, while the bottom yarn package 13 in the magazine 12 is released so that it falls on a downwardly and inwardly and rearwardly inclined slide 23. An active one According to Fig. 6, the yarn storage body 13a is in a pocket 24 at the lower end of the chute 23, from where the yarn Y 'follows is pulled up to get to the associated package 25 on the upper - '■' part of the I.Iaschine.

As soon as the thread package 25 in question has reached the desired diameter, the winding head 11 in question is automatically stopped by known means not shown here, whereupon the operator removes the finished thread package from the thread package carrier 26 in order to place it on a base 27 which extends lengthways of the upper part of the machine 10 near the rear thereof, so that the next yarn carrier or bobbin 30 can be inserted into the support structure 26. Each of the resulting yarn packages 25 rests on a winding roller 31 which is provided with a helical hat of opposite threading direction, which in a known manner serves to move the yarn Y ¹ to and fro with respect to the resulting yarn package 25.

On its way from the active yarn supply body 13a to the yarn body 25 on the winding head 11, the yarn Y ^J passes through according to Pig. 6, one after the other, a lower guide eye, two grids or grids a, a ', a clamping device with a driven rotating disc b · and a movable, elastically pretensioned clamping member b' that works together with the disc,

009818/0785

- 12 - 1A-29 576

The yarn X ^{1 then} runs upwards through a suitable blade catcher c, which is also referred to as a passage plate, in order then to pass a slotted upper guide plate 55 which converges towards the rear with respect to a guide plate 56 adjacent to it.

The lower guide eyelet 54 is carried by a lower guide plate which diverges outwards and forwards with respect to the guide eyelet. The grids a and a 'serve as sensing organs; one of the grids is biased against the other grid, and if there is no strand of yarn between the two grids, or if the tension of the yarn is too low, the grids a and a ¹ engage each other to a greater extent, so that the gripping and linking organs of the monitoring device 40 shown in FIGS. 1, 5 and 5 are actuated as soon as this device is brought into alignment with the winding head 11 in question in a manner still to be explained.

The loop or knob catcher c, the test organ acts, is designed in the usual γ / iron so that it makes it possible detect thicker sections or knobs in the yarn Y ' and to cut through the yarn as soon as a thickened head or the like runs into the knob and mode of action of such a bubble catcher is known a more detailed explanation should be superfluous. It should only be noted that the automatic Bobbin catcher associated with the winding machine c comprises a blade which is biased against a plate over which the yarn passes; when a thicker yarn section arrives, the blade will

009018/0785

- 15 - U-29 376

moves the nub against the plate so that the yarn is held in place and is severed

The monitoring device 40 is in the form of a carriage or carriage which is arranged on the rigid suction line 20 and is movable along this suction line, so that the suction line forms a guide for the monitoring device. the Device 40 comprises a knotter 45 and, as shown in FIGS. 3 and 5, two automatically movable along an arcuate path G-arnansaugorgane 46 and 47 of hollow or tubular construction, which are in communication with the interior of the housing of the device. The device 40 is powered by an electric motor 50 reciprocated along the rigid suction line 20, and when the monitoring device is in alignment with a Rinsing head 11 comes, according to FIG. 3, an associated valve plate 51 is automatically pivoted to establish a connection between the rigid suction line 20 and a suction line 52 supported by the device 40, so that the orifices the G-arnfangrohre 46 and 47 acted upon with a negative pressure will.

As soon as the yarn Y ^{1 is} severed at one of the winding heads 11, this fact is established in the described method with the aid of the grids a and a ¹ , and this automatically causes the monitoring device to stop at the winding head 11 in question as soon as it is Then the catching tubes 46 and 47 move forward in opposite directions, ie the upper catching tube 46 moves along an arc downwards, while the under © catching tube

00Ö818 / 078S

- 14 - 1A-29 376

moved upwards along an arc. Here, the mouth of the jpangrohrs 47 comes into the immediate vicinity of the passage point between the winding roller 31 and the resulting yarn package 25, the winding roller 31 moves in the opposite direction compared to its normal direction of rotation, and the yarn end hanging down from the yarn package 25 is supported by the Catch tube 47 sucked in. At the same time, the catching tube 46 moves downward until its mouth is close to or between the grids a, a ¹ and the guide eyelet 34 in order to catch the lower end of the yarn which extends from the active yarn supply body 13a.

The two catch tubes 46 and 47 then return to their in Pig. 5 back to the rest position shown in order to pull the yarn ends of the yarn bodies 25 and 13a past each other, while the knotter 45 automatically moves forwards or inwards in order to grasp the crossing yarn ends and to connect them in a known manner. The knotter is then withdrawn and the monitoring device 40 moves to the next winding head 11 at which the yarn Y ^{1 may} have been severed.

As soon as the yarn supply of the active supply body 13a is exhausted, a sensing element 55 which is under tension and which is arranged near the associated pocket 24 detects the lack of yarn on the relevant bobbin in order to deliver a trigger mechanism of known type shown press so that the empty bobbin is discharged from the lower part of the chute 23 and the ash 24 in order, as shown in FIG. 5, to a collecting container

009818 / Q78S

156049b

1A-29 376

56 to fall.

When an empty bobbin is detected by the sensing element 55 in one of the winding heads 11, the lowermost supply bobbin 13 is also automatically released from the relevant magazine 12, so that this bobbin falls into the chute 23 in order to reach the To step in place of the previously used active yarn supply body 13a. The yarn Y of the new bobbin extends here from the yarn catcher tube 17 downwards so that it is from the yarn catcher tube 46 (Pig, 5) can be detected as soon as the monitoring device 40 again in alignment with the winding head concerned 11 is coming.

It should be noted that the diverging leading edge portions of the lower guide plate 57 of FIG. 6 serve to guide the yarn into the. Guide eye 34, while the diverging leading edges of the upper plates 35 and 36 have the task of guiding the yarn into the slotted rear part of the plate 35 after the yarn has been knotted again in the manner described. Of course, the grids a and a are automatically separated from each other, and the tensioning members b and b 'are also lifted from each other when separate yarn ends are tied again, whereupon these parts are automatically returned to their normal position, so that the yarn automatically between the grids a, a ¹ and the tensioning elements fe, b »and is also passed through the knob catcher e as soon as the strand of yarn hanging down from the receiving body 25 has been linked again in the manner described by the monitoring device to the strand emanating from the stock body 13a.

From the above description it can be seen that an excessive accumulation of fiber waste and other light material or of foreign bodies on the upper end of the yarn catcher tube 17, on the linden of the yarn catchers 46, 47 »on the plates 35, 36, 37, on the guide eye 34 , on the grids a, a ', between and on the tensioning elements b, b ¹ as well as on the top catcher c can lead to errors in the yarn to be wound up, and that in particular the activity of the grids a, a', the tensioning elements b , b ¹ , the knob catcher c and the sensing element 55 can often be disturbed.The method according to the invention is particularly suitable for keeping these critical parts of the winding machine 10 in a clean condition for long periods of time, whereby the efficiency of the automatic winding machine is increased to an extent as is not achievable with the cleaning devices and methods known up to now.

So far, automatic winding machines of the type described are equipped with a fan that is on a Guide moved along each winding machine and has a single air delivery nozzle, by means of which a single one does not oscillating air flow at a relatively low speed is released, which covers a relatively large area. This air flow makes it possible to remove certain fiber waste easy-to-reach "rush the automatic winder to remove, but it reaches the more critical areas of the winder, especially the one on the lower middle Part of Fig. 6 described yarn guide, sensing and testing elements, not to a sufficient extent.

According to the invention it is provided that several fine air streams of high speed along the machine or move machines 10, these air flows transversely to this Make swinging movements in the direction of movement. These fine air currents of high speed are so on the machine directed that they face the critical parts of the machine as well as moving near less critical ropes to remove fiber waste and excessive build-up of Prevent fiber waste on the critical parts of the machine. In connection with the described ^ experience to blow away of fiber waste from the critical surfaces of the winding machine are the fiber waste removed from the critical surfaces, which are deposited on the floor, sucked off from the floor and fed to a collection chamber, which together with the air currents moved at high speed. The following is a suitable one Device for carrying out the method according to the invention described.

The fine, swaying air currents from high speed with the help of a total of 60 produced above the winding machine and together with a movable blower, a total of 61 designated device for vacuuming the soil brought into effect. With the exception of the hanging blowguns and the Means for pivoting the same back and forth can be the blowing device 60 be designed as in the patent

VIIa / 76c
(Patent application P 29 946 /) of August 1, 1962 is described. The entire movable blowing device 60 can furthermore according to FIG

86g the patent (patent application P 35 780 Vila /; our

^ calibration: 1A-29 107).

The portable vacuum cleaner 61 for cleaning the floor may be as described in US Pat. No. 1,162,992 or US Pat in the patent (patent application P 29 240 X / 36 (^ given is. Therefore, the following is a. Description of the cleaning devices 60 and 61 are given only insofar as this is necessary for an understanding of the invention. The moving ones Cleaning devices 60 and 61 are arranged on an elongated guide 62 which extends above the machine or Machine row 10 extends in the longitudinal direction.

The movable blowing device 60 comprises a blower housing 65, which is in the form of a helix in outline, with two outwardly projecting, curved, essentially diametrically opposite channels 66 and 66, the ends of which are curved downward and which carry movable hollow couplings 67 and 67 ', which according to FIG 5 at 70 and 70 'articulated to the couplings and via flexible collars 71 and 71' to the channels 66 and 66! are connected.

Several of air flowed through them at high speed Blowpipes, each of which has a relatively small diameter and is made of a rigid material, e.g. a plastic, are suitably attached to the substantially closed lower end of each coupling 67 and 67 ' and are in communication with the interior of the coupling concerned. In the present pail there are three blowguns 73, 74 and 75

009818/0786

- 19 - 1A-29 376

connected to the coupling 67 so that they extend downward from the coupling, and three more blowpipes 73 ', 74' and ^75f extend downward from the coupling 67 '. The .Blowpipes 73 to 75 and 73 'Ms 75' are connected to the couplings 67 and 67 'with the help of flexible tubular connections 76, so that the blowpipes can give way if they hit any parts of the fascine or during their longitudinal or pivoting movement come into contact with the operator. The arrangement of the blowpipes and their nozzles opposite the automatic winder 10 will be described below.

The G-housing 65 contains one for generating an air flow of high speed suitable fan runner 80, the above of the associated electric motor 81 is arranged, which is supported by a vague 82. The carriage 82 carries wheels 85, which run on the guide 62, and two of these wheels are driven by an electric motor 86, which can be reversed can, depending on whether the guide 62 has free ends or is designed as an endless guide. "

The housing 65 is on the upper part of the electric motor 81 is disposed and attached thereto, and with a lower or middle part of the motor 81 is an annular plate 90 connected to which a ratchet wheel 91 is attached, which can be rotated stepwise. The ratchet wheel 91 carries an annular Filter 92, the upper edge of which has a sealing effect on the lower Yfand of the housing 65 is applied. The filter 92 is used for cleaning the air that is sucked into the housing by the fan 80, so that the air through the channels 66, 66 »

009818/0785

- 20 - 1A-29 376

the couplings 67, 67 'and the pipes 73 to 75 and 73' to 75 · " is delivered.

So that the ratchet wheel 91 and the filter 92 can be rotated step by step, and to pivot the clutches 67 and 67 'to and fro in the lateral direction, these parts are connected to a relatively small electric motor 95 which, at the downwardly protruding outer end of the channel 66 of the blower housing 65 and is offset somewhat inwardly according to FIGS. 5 and 7. Referring to FIG. 2 and 7, a length-adjustable rod 96 extends from a crank pulley e on the shaft of the motor 95 to the upper end of a ^iJ -ebels 97 which is rotatably mounted between its ends on a pin 70 so that the coupling 67 back and can be swiveled. The lower end of the lever 97 is connected as shown in FIG. 7 by rods 101 and 102 and a pivot arm 103 to a vVinkelhebel 104 which is mounted on the underside of the annular plate 90 and carries a pawl 105 which engages with the spring force Ratchet wheel 91 is held.

The rods 101 and 102 are preferably adjustable in length and preferably adjustable with the arm 103 and the angle lever 104 connected so that the stroke length of the pawl 105 relative to the coupling 67 can be varied. The arm 103 is on the Plate 90 stored. The couplings 67 and 67 · are adjustable in length Rods 106, 106 and 107 interconnected. The rods 106 and 106 »are adjustable with swivel arms 110 and 110 · which are mounted on the underside of the plate 90, and · the ends of the rod 107 are adjustable with the

009818/0785

- 21 - U-29 376

Swivel arms 110 and 110 'connected so that the range of motion the coupling 67 'is adjustable with respect to that of the coupling 67.

In order to prevent clogging of the annular filter 92, aligned mouths of blowing and suction nozzles 113 and 114, which are attached to the housing 65, are arranged in the immediate vicinity of the inner surface and the outer surface of the filter 92, respectively. The blower nozzle 113 serving for cleaning the filter is connected by a line 115 to the air suction duct 66. Another line 116 connects the suction nozzle 114 serving for cleaning the filter with the inlet side of the housing 120 of the vacuum cleaner 61 for cleaning the floor.

The blowguns 73 to 75 and 73 'to 75 ^! have different lengths and carry blow nozzles 73a to 75a or 73a ¹ to 75a ¹ with air outlet openings of relatively small diameter (about 12.5 to about 32 mm), which are arranged as close as possible to the parts of the winding machine to be cleaned, in order to circulate fine air flows at an exit speed of at least about 1500 m / sec onto the relevant parts and past these parts, while the nozzles move along the machine and are swiveled back and forth. Good results are achieved when using nozzles in which the diameter of the outlet openings is between approximately 16 and approximately 30 mm.

The nozzles 73a and 74a are swung back and forth at a short distance above the horizontal plane of the magazine 12 and from the front of the magazine to points that

009818/0785

- 22 - 1A-29 376

are offset far enough to the rear of the magazines so that the fine air currents according to Pig. 6 impinge on the critical working parts 17, 22, 34 to 37, a, a », b, b ¹ and c of the various winding heads 11. Although the nozzles 73a and 74a move along similar paths, it should be noted that the nozzle 73a is angled from the nozzle 74a so that the air streams from the two nozzles are discharged in different views. This arrangement not only ensures that many parts of the machine are hit at different angles by high-speed air streams, but it also ensures that parts of the machine which are shielded at their top by other machine parts or by the packages 25, the air flow discharged through the nozzle 73a. The inclined arrangement of the nozzle 73a also causes the air flow to be directed to remove fiber waste from the working parts of the knotting device 45 of the monitoring device 40.

The nozzle 75a is at a greater height above the ground swung back and forth as the nozzles 73a and 74a, and this nozzle moves further inward towards the machine so that it a fine stream of air at high speed on the take-up rollers 31, packages 25 and associated supports directs. To the air flows from the nozzles 73a and 74a in removing paser debris from the mentioned critical To support working parts in the lower part of the winding machine, further nozzles 73a », 74a 'and 75a' are at different heights arranged and curved inwardly as shown in FIG. 5 that they are the

O09818 / Ö78B

_ 23-1A-29 376

The back of the machine 10 faces so that fine air currents delivered at high speed essentially horizontally while the daes are generally in vertical planes and be swung around.

It should be noted that the air flow from the nozzle 73a ¹ on the lower part of the monitoring device 40, the active yarn storage body 13a, the pockets 24 intended for it and the sensing elements. 55 occurs, by means of which it is determined whether the yarn supply of the yarn body 13a has been used up.

about 2400 and about 2600 respectively.

When the nozzles 73a 'Ms 75a · those in Fig. 5 with dashed Assumed position indicated by lines, their distance from the pockets 24 or the grids a, a »or the yarn catchers 46 and 47 about 300 mm, about 450 mm and about 380 mm, and the velocity of the air on these ropes was the Machine about 1800 or about 1050 or about 1300 m / min. At this Arrangement of the air nozzles and the specified air flow rates all critical parts and the adjacent zones have been cleaned very well and to such an extent that that the automatic winding machine 10 could be operated properly, and that it was not necessary to stop it, to be able to carry out cleaning by hand; after each cleaning carried out by hand, the machine could be operated for 24 hours or more. Under under these circumstances, the required manual cleaning could be avoided an automatic winding machine with 50 winding heads 11 at intervals of about 24 hours with the aid of one by hand lead through the compressed air hose within 2 to 3 minutes.

Until now, the winder shown here had to be stopped and cleaned by hand every 4 to 5 hours, and every Such cleaning required about 15 minutes for the machine with 50 winding heads thus leads to an increase in the efficiency of the automatic winding machines, so that there is an increase in production can be achieved.
